Inter-Context Trust Bootstrapping for Mobile Content Sharing

Monday, July 30th, 2007

Today I’ll present (ppt) part of our work on UTIFORO (previous post) at CAT.

Consider a community of users who share digital content through their handheld devices. If there are many such users, and no (or a very poor) means of filtering, they may suffer from content overload. To avoid this, it would be preferable if users could effectively select content that both lies within their range of interests and comes from sources that are trustworthy. Users may do so by running trust models on their devices. A trust model is a piece of software that keeps track of which devices are trusted and which are not.

This talk will look at how a trust model running on device A determines the extent to which A should initially trust device B in a given context (content category). It does so by considering two cases: in the first, A does not know B at all; in the second case, A knows B but in contexts other than that of interest. For each of those two cases, this talk will discuss the most recent proposal that improves on existing solutions (TRULLO and distributed propagation), and will also attempt to suggest new research directions (such as private collaborative filtering – post & more).

Privacy in ubiquitous and home computing

Monday, July 30th, 2007

A talk by Jean Camp at BT Adastral Park on the 1st of December.

The talk discusses privacy in ubicomp as a design, social, technical, and policy issue; outlines the research program at IU that is designed to meet the technical and social challenges of using sensor networks as a monitoring technology.

Social Tapestries: Mobile spatial annotation

Friday, July 27th, 2007

From this post: “Raj Kottamasu, a Master in City Planning Degree Candidate at the Department of Urban Studies and Planning at MIT has posted his thesis, Placelogging (PDF 12Mb) online which contains a study of the Social Tapestries projects (among others) in relation to urban planning. The thesis looks at Mobile spatial annotation and its potential use to urban planners and designers and is an impressive, readable and stimulating piece of research”.

Mobile Web 2.0 in London

Friday, July 27th, 2007

The first European conference on Mobile Web 2.0 will be in London (!) on the 18th and 19th of September. It will gather some of the best thinkers and doers. Agenda. More info here.

Collaborative computation

Tuesday, July 24th, 2007

An interesting example of mobile surveillance system. Would there be the possibility to introduce collaboration among the robots?


Bio-inspired morphing-wing micro aerial vehicle

“Aerospace engineering students at TU Delft, together with the Department of Experimental Zoology of Wageningen University designed the RoboSwift. RoboSwift is a micro airplane fitted with movable wings, inspired by the common swift, one of nature’s most efficient flyers. The micro airplane will have unprecedented wing characteristics; the wing geometry as well as the wing surface area can be adjusted continuously. This makes RoboSwift more maneuverable and efficient. Resembling the common swift, RoboSwift will be able to go undetected while using its three micro cameras to perform surveillance on vehicles and people on the ground. Furthermore, it can be employed to observe swifts in flight, thus enabling new biological research.”

More details here.

The UltraSwarm project (another intersting project is from the University of Sussex) is another example of a possible application in which mobile collaborative computation can take place among robots (helicopters).

“This study will investigate methods for achieving useful and controlled flocking in a swarm of small co-axial rotor helicopters by developing an accurate model of the vehicles and their aerodynamic interactions, and using this in simulation to optimise flocking performance before real-world testing.
The project combines two key ideas:

* Using biologically inspired rules of group behaviour (flocking) to enable a group of UAVs to control its own motion
* Wirelessly networking the swarm members together to form a single powerful computing resource

The term flocking, derived from flocks of birds, refers to the coordinated movement of a group of individuals such that they move with approximately the same velocity and inter-agent distance.”

London gets free Wi-Fi

Tuesday, July 17th, 2007

“…A Adobe Acrobat X Pro Sale free metropolitan Wi-Fi network has been launched in London, continuing the gradual trend toward free public wireless Internet access in Europe and the United States….The group behind (…) to offer free Wi-Fi access to businesses and the public along a 13.6-mile stretch of the River Thames.”

Taking your meds? Sensors will know

Wednesday, July 11th, 2007

An interesting article on wireless sensors for health monitoring. The bottom line is that “…while the market for it is not easily measured, few doubt it’s growing”

“…High-tech monitors, Webcams and GPS devices are helping caregivers keep track of elderly parents from afar. Such technology, some believe, can help people straining under family responsibilities.” It’s interesting, that there are already quite a few companies providing health monitoring service based on wireless sensors.

Mobile Social Shopping

Wednesday, July 4th, 2007

The Utiforo project that some of us here are involved in (see previous posts) is sub-titled “pervasive computing support for market trading;” the broad goal of the project is to bridge the gap between online and offline commerce by researching the applicability of trust to this scenario. One of the sub-goals of our partners at Sussex is to develop a navigation kiosk application, to capture user policies as they roam shopping centres.

However, I’ve read a couple recent articles that show that commercial applications are most likely one step ahead: Wishpot, for example, allows users to upload and share items of interest (via mobile phone text messages or photographs) to their online profile. They can then use their profile, along with various social-network features, to research prices, view user-ratings, and receive recommendations. Other commercial applications include Kaboodle, Stylehive, Zlio, and MyPickList. One site even quoted that these services will bring about the end of impulse buying (by allowing users quick access to price comparisons and product quality assessments)!

MobileMonday in BCN: Mobile Web 2.0

Tuesday, July 3rd, 2007

Yesterday I was at the MobileMonday Barcelona event. Three speakers talked about ‘Mobile Web 2.0′:

Patrick Lord introduced his company’s main application – MobiLuck. It’s a short range wireless messaging application. MobiLuck allows you to detect all Bluetooth devices around you and to store a mini-profile in your Bluetooth name. The mini-profile can include for example your nickname, gender, age and phone number (dating profile) or your first name, last name, company and phone number (business profile). Your mini-profile is detected instantly by other MobiLuck users. You can then send a message (or your picture or your business card) with your mobile in a few clicks, for free, with no need of the recipient’s phone number.

Lucia Garate (of Vodafone R&D, Madrid) presented Vodafone Betavine that aims to help developers create new and innovative services using mobile communications APIs.

Ajit Jaokar (London) listed some of the concepts behind its latest book (Mobile 2.0).

Similar events are offered in London.
